Customer Reviews & Comments
The Shinn brothers are legendary in information security, so when I saw this book, I made sure to put it on the top of my airline reading list. If you ever watch someone closely that is trying to troubleshoot a computer, network, or firewall, you quickly realize fault detection and root cause determination are skills very few people have. I watch people change two things and reboot, or try the last thing they just tried again and just shake my head. The book is not just about troubleshooting, it includes setup, network theory, and proper design as well. However, chapter 4 should be required reading for anyone that is allowed near a computer with privileged access, windows or unix. If this book gets revised I would love to see the troubleshooting chapter expanded, that is critially important information.
